MILES DE WITT, OF WHITE SULPHUR SPRINGS, NEW YORK.

BROODER.

. Application filed July 1, 1911, Serial No. 636,378. 'Renewed October 7, 1913.

To all whom it may concern Be it known that 1, MILES DE \Vrrr, a citi- Zen of the United States, residing at White Sulphur Springs, in the county of Sullivan, State of New York, have invented certain new and useful Improvements in Breeders; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to breeders and has for an object to provide a heating mecha nism that will reduce crowding and consequent smothering of the chicks.

A second object of the invention is to provide a breeder in which the heat from the heater is caused to travel through a circuitous path andfinally play upon and heat an outer cylindrical cap,the heat during this travel through the circuitous path, heating a series of metal caps so that fluctuations in the heat from the burner will not be transmitted directly to the outer cylindrical cap and thus a more uniform temperature is maintained in the breeder.

With the above objects in view the invention consists in certain novel details of construction. and combination of parts hereinafter fully described and claimed, it being understood that various modifications may be made in the minor details of construction within the scope of the appended claim.

In the accompanying drawings forming part of this specification :Figure l is a horizontal sectional view through the breeder. Fig. 2 is a vertical sectional view taken on the line 22 Fig. 1.

Referring now to the drawings in which like characters of reference designate similar parts, the breeder casing is shown to coi'nprise a circular bottom 10, a cylindrical side wall 11, a conical top 12, and an integral horizontally disposed false bottom or diaphragm 13 which is centrally provided with a circular orifice 14:. A lamp 14 of any preferred construction is mounted on the bottom and is preferably arranged so that its chimney extends up through the opening 14 and delivers the heat from the lamp into the compartment above the diaphragm. A hinged door 14 permits of the insertion and removal of the lamp from the casing. A cap 15 registers with the opening 14 and forms a battle for the heat from the lamp or burner, the edges of the cap being spaced Specification of Letters Patent.

from the diaphragm and being secured thereto through the instrumentality of a plu= rality of angle iron legs 16 which are riw eted or otherwise secured to the diaphragm. The object of spacing the cap fromthe diaphragm is to permit of heat escaping underheath the lower edge of the cap. Surrounding the cap is a cylindrical baffle 17 the lower edge of which is provided with a se curing flange 18 which is riveted or otherwise secured to the diaphragm. The battle 17 is imperforate and may be formed integral with the diaphragm if desired, and further is of such height that its upper edge is substantially flush with the top of the cap 15. Heat escaping from underneath the cap is deflected by the bafile and caused to travel upwardly between the battle and the cap. An intermediate cap 19 similar in construction to the inner cap already described, is arranged to surround the baffle and is spaced therefrom in all directions, the lower edge of the intermediate cap being spaced from the diaphragm and being equipped with securing angle irons 20 which are riveted or otherwise secured to the diaphragm. By virtue of the intermediate cap, heat escaping over the upper edge of the battle is directed downwardly and escapes underneath the lower edge of the cap 19. An outer cap 21 is ar ranged to form a closure over the intermediate cap, and is spaced therefrom in all directions, the lower edge of the outer cap bearing upon and being seemed in any preferred manner to the diaphragm. A nipple draft line 23 which extends through the top 12 of the breeder casing. By virtue of the outer cap, heat escaping from underneath the intermediate cap will be directed upwardly over the top of the intermediate cap 1t23nd will finally es ape through the draft From the above description it is obvious that the heat from the burner is caused to travel through a circuitous path, and further that before arriving at the outer cap, both the inner and intermediate caps together with the battle will be heated, this construction preventing fluctuations in heat from the burner being transmitted directly to the outer cap against which latter, it may be here stated the chicks are supposed to huddle for warmth. By virtue of the caps described, the heat from the burner will be distributed uniformly in all directions so that the outermost cap is uniformly heated throughout its length and thus the chicks may nestle themselves around the entire circumference of the outer cap and all receive a like heat from the outer cap, and thus crowding of the chicks is obviated.

An annular rail 9Ais secured to the top of the outer cap and in any preferred manner, and from this rail depends a cylindrical curtain 25 which extends to the diaphragm and forms a hover. The hover is slit at intervals to permit of passage of chicks therethrough.

That is claimed, is

A brooder including a casing having a false bottom in the nature of a diaphragm, a heater on the casing bottom projecting upwardly through an opening in said diaphragm, a cap carried by said diaphragm housing said heater above said diaphragm 7 and having the lower edge spaced from said cap housing and spaced in all directions from said intermediate cap and having the lower edge bearing upon and secured to said diaphragm, there being a vent in said outer cap.

In testimony whereof, I aflix my signature, in presence of two witnesses.
